I've been hearing a lot about how powerful the Stormbolter is, magnified by special ammunition. This got me thinking about a quick way to change the stormbolter without totally destroying it.
I propose that instead of 2 hits per DoS, up to RoFx2, the stormbolter gets 1 hit per DoS up to RoFx2. You get the same number of potential hits, but it should bring average damage down to more manageable levels.
